IFNG and osteosarcoma: Anti-human IL-12 neutralizing monoclonal antibody significantly reduced NK92-mi production of IFN-γ in response to supernatants from hu-IL-12 transduced osteosarcoma (143B) (p = 0.016455), Ewing sarcoma (A673) (p = 0.006253), and rhabdomyosarcoma (RD) (p = 0.000006) cells (Fig. 2c).
